초록

We report measurements of the exclusive cross section for e(+)e(-)-> D(0)D(-)pi(+) over the center-of-mass energy range 4.0 GeV to 5.0 GeV with initial-state radiation and the first observation of the decay psi(4415)-> D(0)D(-)pi(+). From a study of the resonant substructure in psi(4415) decay we conclude that the psi(4415)-> D(0)D(-)pi(+) decay is dominated by psi(4415)-> D (D) over bar (*)(2)(2460). We obtain B(psi(4415)-> D(0)D(-)pi(+)(nonresonant))/B(psi(4415)-> D (D) over bar (*)(2)(2460)-> D(0)D(-)pi(+))< 0.22 at 90% C.L. The analysis is based on a data sample collected with the Belle detector with an integrated luminosity of 673 fb(-1).
